					<para>
    Possible surface brightness selection effects in the redshift catalogs
    of the Canada-France Redshift Survey are investigated through
    comparisons of subsamples of the data. Our analyses demonstrate that
    the securing of redshifts is independent of possible biases arising
    from surface brightness effects and/or differing galaxy morphologies
    and orientations. The unusual geometry of the mask designs for our
    spectroscopic observations also do not produce any significant bias.
    There is, however, a bias at the highest and lowest redshifts,
    especially for absorption-line galaxies at z>1 and z&lt;0.2, due to the
    adopted spectral range (4250-8500A). Apart from the latter, we
    conclude that our sample of identified galaxies is an unbiased
    subsample of the original photometric catalog and is essentially
    limited by I-band flux density (17.5&lt;I_AB_&lt;22.5). Finally,
    spectroscopic data for the remaining CFRS field is presented. Data for
    272 objects in the 0300+0000 field are given.</para></abstract>
